Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases
engine power over that developed by the normally-aspirated engine. The charge air cooler (which resembles a radiator)
is located between the turbo- compressor and inlet manifold.
Fuel system
The engine is equipped with a multiport fuel injection system.
